Mill Spring Ag Center


The Mill Spring Agricultural Center is the home of agriculture in Polk County. It was born out of the abandoned Mill Spring School, a 40,000 square foot building abandoned in 1998 after serving as a primary and high school since the mid ’20s. See More of the School’s History. Over the past 4 and a half years and through over 1,000 volunteers and counting, the building is slowly being restored into a beacon for its community. The Mill Spring Ag Center is owned and operated by the Polk County Soil and Water Conservation District and is not tax funded. Funding for operation is solely derived by refurbishing and then renting out old classrooms as offices and through fundraisers, donations, and grants.

The Ag Center features many amenities and programs:
